Region Naming

Region names are initially derived from either:

the name of the track for which they were recorded, or

the name of the embedded/imported file they represent.

Whole File Region Names

These are not audio files, but regions that represent the full extent of an
audio file. Every time a new recording is done, or a new file is imported
to the session, a new region is created that represents the entire audio
file. This region will have the name of the track/playlist/original file,
followed by a "-", then a number plus a dot and then a number.

For recorded regions, the number will increase each time a new recording
is made. So, for example, if there is a track called
Didgeridoo, the
first recorded whole file region for that playlist will be called
Digderidoo-1. The next one will be Digeridoo-2 and so on.

For imported regions, the region name will be based on the original file
name, but with any final suffix (e.g. ".wav" or ".aiff") removed.

Normally, whole file regions are not inserted into tracks or playlists,
but regions derived from them are. The whole-file versions live in the
Editor's region list where they act as an
organizing mechanism for regions that are derived from them.

Normal Region Names

When a region is inserted into a track and playlist, its initial name will
end in a version number, such as .1. For a recorded region,
if the whole file region was Hang drum-1, then the region in
the track will appear with the name Hang drum-1.1. For an
imported region, if the whole file region was Bach:Invention3,
then the region in the track will appear with the name
Bach:Invention3.1.

Copied Region Names

Duplicating or splitting a region creates new region(s) that
are based on the same original files. Hence, they share the same base name (in the
exemple above, Hang drum-1), but their version number will be incremented
each time. Duplicating Hang drum-1.4 by left
dragging it will create a new region called Hang drum-1.5. Splitting
Hang drum-1.5 by hitting the S key will remove the
Hang drum-1.5 region and create two shorter regions named
Hang drum-1.6 and Hang drum-1.7.

Renaming Regions

Regions can be renamed at any time using the region context menu : right click > name_of_the_region > Rename... .
The new name does not need to have a version number in it (in fact, it probably
should not). Ardour will add a version number in the future if needed (e.g.
if the region is copied or sliced).
